Multiplexer / Demultiplexer

With the NetAcquire Multiplexer Option, distributing serial data in real time has never been easier or more reliable. Now you can harness the power of the Internet to transport your specialized data and signal timing over commonly available networks.

The NetAcquire Multiplexer option, added to a NetAcquire server, reads a collection of electrical input signals and converts the resulting data streams into network packets. It then sends this aggregate data stream out over a network. A second NetAcquire server reads the data from the network and reconstitutes the data back into the equivalent electrical output signals at a remote location. It's that easy!

Reliability

The integrity of your data is maintained throughout the distribution process. NetAcquire Multiplexer preserves the relationship of the signals from the source side to the destination side. The time correlation of the source signals also is maintained and reconstituted on output.

NetAcquire Multiplexer has a unique output channel rate adaptation that prevents serial bit slips and data padding due to input-to-output timing mismatch.

Unlike traditional time division multiplexer (TDM) systems, the NetAcquire Multiplexer option does not require a dedicated T1 or T3 connection, and is much more bandwidth-efficient because it uses packet-based technology. This saves network costs and frees up bandwidth for other uses.

NetAcquire Multiplexer also eliminates the restrictions of traditional point-to-point communications. Configurable packet routing supports transferring the same data to several destinations simultaneously. In addition, groups of channels from any number of different sources can be combined at a single destination. This routing flexibility reduces both infrastructure and management costs.

Features

• Transfers data signals reliably in real-time between two or more sites connected only by a network

• Supports different types of data signals, including serial, analog, digital, and voice with a mix-and-match input/output architecture

• Low data transport latency and high throughput

• Bidirectional capability on all channels

• Automatic compensation for variable network delays

• Robust communication with automatic detection and correction of bit errors that may occur during network communication

• Transfers IRIG timing when used with the NetAcquire IRIG option

• Quality of Service (QoS) prioritization of channel priorities to maintain important channels even when network throughput decreases

• Automatic network reconnect if network infrastructure failures

• Load sharing and network path diversity provided by an optional second network interface

• Maximizes available communications bandwidth with optimized multiplexing protocol formats

• Patent pending, output channel rate adaptation avoids bit slips and data padding due to input-to-output timing mismatch

• Automatic source-to-destination data rate tracking avoids error-prone manual configuration

• Transfer of high-accuracy time-of-day data across the network with selectable precision time/data correlation

• Operates transparently with the NetAcquire High Availability Option, allowing automatic multiplexer fail-over to a second NetAcquire server if a hardware or network problem occurs
